10 Best Metal Detectors for Food Industry in 2023

Are you wondering what type of metal detector is best for food industry? If YES, here are 10 best metal detectors for food industry in 2023. In this era where metal particles can easily be found in food due to the different processes food passes through during processing and packaging, the use of metal detectors has become very important.

Metal detectors for food are used for the purpose of consumer protection as mandated by the regulatory authority in the food and drinks industry. Despite maximum care, metallic contamination of food products during the production process cannot be fully excluded.

Metal particles that enter the product during the production process or are already contained in the raw material may cause serious injuries to consumers. No doubt, any food production company that wants to stay in business and avoid unnecessary claims from damages would need to get the best metal detectors.

The truth is that metal detectors for food provide effective protection against ferrous and non-ferrous metals (aluminium, stainless steel, et al). As a matter of fact, metal detectors can be installed in every step of the production process and can be used for many different applications, e.g. for the inspection of bread and bakery products, meat and sausage products, fruit, vegetables, dairy products, spices, sugar, and the likes.

Please note that in addition to protecting consumers from ingesting metal particles from food, metal detectors also are used to protect machinery from wear and tear. Even the smallest metal particles can lead to machinery failure. Expensive repairs and production downtimes are the consequences, often followed by revenue decrease.

Having said that, it is important to state that there are several types of metal detectors that operate with different detection methods in the food industry, and here are some of the best metal detectors you can get for the food industry.

What are the Best Metal Detectors for Food Industry in 2023?

  1. Corrosive Resistant Magnetic Liquid Trap

Many industries are tasked with handling highly acidic or corrosive materials as part of their standard product flow, and it is a challenge to find metal separation products that can maintain a high level of performance while also being able to resist corrosion.

Bunting has responded to the needs of customers working in the food, chemical, and oil industries and developed a new corrosive resistant magnetic liquid trap in order to provide a solution to this problem. The CR-MLT is made from a special alloy material that holds up against acidic, corrosive materials, resulting in a drastically extended lifespan compared to the traditional liquid trap. It resists corrosion and pitting that would otherwise cause severe damage to other traps over time.

The CR-MLT is able to handle even the most difficult to flow products, utilizing a 2” diameter magnetic load to achieve complete reach out. It has a built in manual self-cleaning ability, meaning that once the flow of product has been turned off, the operator simply needs to remove the lid and use the metal detectable wiper to clean off the center magnet cartridge.
